The need for adjustment of the transfer and fusing subsystems of an electrostatographic machine is determined by adjusting the machine's process control parameters until density reading of an untransferred toner image of a test patch are within specification, or are otherwise acceptable. The toner image is transferred and fused to an image receiver sheet, and deficiencies in the images on the receiver sheet indicate the need for adjustment of the transfer and/or fusing subsystems.
